<h3 id="rationale">Rationale:</h3>
<p>ShellCheck found a command name containing an especially unusual
character like a tab or linefeed. This is most likely due to a syntax
issue.</p>
<p>In the example, this was due to a Python style documentation string,
which a shell will merely interpreted as a multi-line command name
sandwiched between two empty strings.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>If you have a command name that <em>does</em> contain a tab or
linefeed you can ignore this message, but... wow.</p>
